I just brewed this! I used this recipe which has a lot of great discussion. I used cocoa powder & peanut butter powder in the secondary, and added cocoa nibs a week later (sanitized by soaking in as little vodka as possible overnight).

I've used 250g cocoa powder in 25L of Robust Porter a number of times (both at flameout and added after primary), and it comes out tasting very dark-chocolatey. I haven't used nibs before, so I can't give you a comparison.

I'd be very interested to hear how you plan to get the peanut butter flavour - I've considered making a similar beer, but have been put off by the problems associated with using actual peanut butter.

Thanks, I've not seen or heard of powdered peanut butter before - I'll have to keep an eye out for it!

Yes the PB2 is fantastic, I ordered two chocolate & pb ones and one PB one from amazon (only used the PB one so far but planning to use the chocolate ones in a later batch). I added enough water to pour and boiled for a short while, then cooled and added to secondary. Chime in on that forum with your results!
